高考英语写作错点分析·否定模糊型有的同学对于否定的概念模糊，不知如何否定，有时会写出不合规则或有异义的句子。1. 我认为没有必要买大的。 误：I think it's not necessary to buy the bigger one.正：I don’t think it is necessary to buy the bigger one.析：有些动词如think, believe, expect, suppose, imagine, guess, fancy等的主语是第一人称单数且一般现在时，表示否定的观点应用I don’t think…，而I think… not则属于汉语式表达习惯。2. 我们直到天全黑了才到家。误：We arrived home until it became completely dark.正：We didn’t arrive home until it became completely dark.析：此汉语句子里面尽管没有否定词，但until用于肯定句时意为“直到…为止”；用于否定句时，其意为“在…以前”。因此，表示“直到…才”用not…until。3. 如果没有受到邀请的话，我是不会去参加舞会的。误：I’ll not go to the party unless I’m not invited.正：I’ll not go to the party unless I’m invited.正：I’ll not go to the party if I’m not invited.析：unless“除非”、“如果不”，常可用if…not来替换。误句中的条件状语从句双重否定表示肯定，结果与原句意思相反。4. 那孩子不够大不能去上学。误：The child is not old enough not to go to school.正：The child is not old enough to go to school.正：The child is too young to go to school.析：这是学生最容易写错的句子。enough to“足以、足够”。原句中“不够大不能去上学”意思是“不够上学的年龄”，故应译为not old enough to go to school。5. 他们两个都不说英语。误：Both of them don’t speak English. 正：Neither of them speaks English. (www.nmet168.com)析：中国学生特别对于all…not 和both…not等这种部分否定结构，很容易理解成全部否定。两者全部否定用neither, 三者以上用none。 6. 开车时再小心也不过分。误：You can be too careful in driving a car. 正：You can not be too careful in driving a car. 析：cannot…too“无论作…也不过分”。 说明:引用此文请注明出处,并请保留该文章链接地址,谢谢~~
